Digimode on 7.079?

What is the digimode on 7.079MHz that sounds a bit like JT65 but appears to be in LSB?

Hi John

I thought that, but I can only hear it on LSB. I need to get JT9 setup obviously.

Maybe someone on JT65 who forgot to switch to USB ??? I have decoded JT65 on LSB occasionally. I usually reply to them with "try USB" and that has worked.

It may also be someone experimenting with the FSQ mode, it does sound a bit like JT65

Waterfall shows both JT65 and JT9 signals.

The 500Hz trace, as seen from 7.079 Mhz LSB is actually a JT9 signal transmitting on 7.076 2500Hz on USB.
Same for 1500Hz trace on waterfall is JT65 signal correctly transmitted on USB on 7.076 Mhz 1500 Hz.

Hard to tell, my guess is most of them is captured using sharp sdr however there are now lots programs available

[VK4WDM]

Sharp SDR

I think that's the program I am supposed to download for my RTL Dongle?

It's JT65, try all the ??.079 on all the HF bands 160m-10m except 30m
